为了解决ZL50型轮式装载机变速器前输出端经常出现的漏油问题,确保变速器质量的稳定,实现装载机产品差异化竞争战略,提高变速器的可靠性,对ZL50型轮式装载机行星动力换挡变速器进行箱体的有限元分析。在装载机变速器处于失速工况下,在Pro/E中建立箱体模型,以Pro/E/mechanica为工具,对箱体各个轴承座进行模拟受力加载,采用适应性P-method技术直接在Pro/E环境下创建有限元模型,模拟了箱体在该工况下的变形,得到了箱体强度和刚度的数值计算结果。着重分析五轴箱体输出端应力、应变及位移响应对密封性能的影响,采取调整箱外筋板分布与内部结构等措施来改善箱体输出端密封性能。分析的结果为变速器的故障诊断提供了参考依据,为该类箱体的设计制造提供了有益的启示。
In order to solve the oil spill problem that often occurs on the front output of the ZL50 wheel loader transmission, to ensure the stability of the transmission, to achieve competitive differentiation strategy of the loader products and to improve the reliability of the transmission, the ZL50 wheel loaders Planetary Power Exchange Gearbox transmission box finite element analysis. When the loader transmission is in stalling condition, the box model is established in Pro / E, and the bearing blocks in the box are subjected to simulated loading by means of Pro / E / mechanica. The adaptive P-method technology is used directly Pro / E environment to create a finite element model to simulate the box under the conditions of deformation, the numerical results obtained box strength and stiffness. The influence of the stress, strain and displacement response on the sealing performance at the output of the five-axis box is analyzed emphatically. Measures such as adjusting the distribution and internal structure of the external rib plate are adopted to improve the sealing performance at the output end of the box. The result of the analysis provides a reference for fault diagnosis of transmission and provides a useful enlightenment for the design and manufacture of this kind of box.
